Nicely machined part, but was fractionally too large diameter to fit my Thorn, no matter how hard I tried to drift it. Ended up having to knock it out and reduce it down a bit before it would go. No

By Luca

Hi, I need to fit an EBB in an old tandem frame.Problem is that the BB shell is 50.6 mm width. If it your EBB is composed of two blocks, is it possible to "cut" the mid-section to make it narrow?Thanks a lot

SJS Customer Service:

Hi,

Unfortunately this is one solid block and we would not recommend that sort of modification to it.

Thanks.

Charge Duster Ss

Do you know if this will fit a charge Duster Single Speed?

SJS Customer Service:

Hi,

Unfortunately we have never had a Charge Duster here so we have no idea what the bottom bracket specification on your bike is I'm afraid. All we can recommend is looking at the dimensions of this item and comparing them to your current eccentric.

Thanks.

Will This Fit A 2009 Rockymountain Hammer 29

HI i am looking for a EEB sleeve for my 2009 Rocky Mountain Hammer, here is the specs http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2009&brand=Rocky+Mountain&model=Hammer+29%22

SJS Customer Service:

Hi,

Unfortunately the specification for the bike you have provided does not give any information on the bottom bracket dimensions and as we have never sold Rocky Mountain bikes or even serviced one of these bikes we're going to have no way of knowing if this Eccentric bottom bracket shell insert will be suitable for your bike or not I'm afraid. The dimensions for this insert are listed within our description so we'd recommend checking those against the bottom bracket shell in your bike first. If they don't match up, all we can recommend is contacting "Greenover Sports" who are the current UK distributor for Rocky Mountain and they may be able to source a replacement but for a bike of that age there is no guarantee.
